As a result of this division, CEN/TS 1317-7 now explicitly focuses on terminals of safety barriers. This new focus enables a more detailed assessment and classification of the performance of terminals, providing a more precise evaluation framework. A key element of the new document is the definition of test methods, which specify the testing procedures. The test code (e.g., TT1.3.110) specifies key test parameters. ‘TT’ stands for Test of Terminal, ‘1’ represents the approach (1-6), ‘3’ indicates the test vehicle mass of 1500 kg (1 = 900 kg, 2 = 1300 kg, 3 = 1500 kg), and the final number represents the impact speed in km/h.
In the new specification, the former performance classes (e.g., P4) are now classified as restraint categories (e.g., T110/1), while the location (e.g., A) has been replaced by a direction category (e.g., BDT = bi-directional terminal).
The definition of lateral displacement has also been clarified, specifying the maximum displacement of the terminal during an impact, both on the traffic side (S) and the departure side (T) of the installation. Additionally, the categories of terminals Z1, Z2, Z3 and Z4 have been newly defined to ensure that the vehicle remains within the distances Za (approach side) and Zd (departure side) of the redirection zone dimensions.
Based on the highest requirements of the Technical Specification, REBLOC has developed and successfully tested two new terminals:
The REBLOC TE 80XA_17.9 is the first precast concrete terminal to comply with the restraint category T110/1 (BDT), previously classified as performance class P4 (A). The goal of this development was to safely redirect vehicles upon impact, thereby preventing rear-end collisions. This solution can be installed on various surfaces, including concrete, asphalt, or compacted gravel. Thanks to its bi-directional design, it can be used on both the approach side and the departure side of a safety installation.
In return, the system-compliant terminal REBLOC TE 80XA_4.1 was specifically developed and tested for the application at the end of a safety installation (UTD = uni-directional terminal – departure). This terminal provides an efficient solution for safety barriers. It meets the highest requirements of the restraint category T110/1 (UTD), former class P4 (D). The terminal ensures the controlled vehicle redirection at the system's end. Its compatibility with both free-standing and anchored REBLOC vehicle restraint systems makes it a forward-thinking and highly cost-effective solution. Due to its short design, this end terminal provides maximum safety for areas where space is limited, making it an ideal addition to the extensive product range.
In summary, REBLOC’s innovative terminals not only meet the requirements of the new Technical Specification but also actively contribute to enhancing road safety through advanced technologies. These new systems help reduce the risk of rear-end collisions, offering a sustainable solution for safer roadways.
